So you are trying to say their is no way to make your skin or bones more resistant to injury? Hilarious. Okay I guess if that's the most intelligent, logical response you are able to provide I won't waste my time with you then. Sounds like your attitude sucks as well. Maybe you are arguing the point with the wrong guy as I personally have had two clinical studies that followed me over the course of years done that proved it, although not on my hands. I was told they were written up in peer reviewed medical journals so you could probably still find them today. Thanks for the laugh.
I'm not gonna give you all the answers but the funniest thing is that you are saying this on a bodybuilding forum which means you are blissfully unaware of some of the simple and pretty well known facts about how this all works within this world. Pssst, I'll tell you one of the lesser know things just cause I'm nice like that- certain AAS are helpful in this process too although that does not refute your incorrect "ugh, me tough bro" assertion because you specifically said "conditioned"
Relevance? You sure jump to your keyboard tough guy shit quick don't you? Yeah I know you scolded me before, you're a real fighter not a keyboard warrior. You may be a legit pro but you act like a big baby, if you don't have anything intelligent to say and can't resist going all strawman because of that you ain't worth my time.
BTW, I kick boxed and retired with a perfect ammy record, but again that's completely irrelevant to the point being discussed
